One thing no one has mentioned that you may not have done yet is to set your current weight and your goal weight to the same number in your diet goals, and SparkPeople will readjust your calorie range for you, to give you a good idea of your long-term maintenance range.
Then you can up your calories slowly, as others have mentioned. You may find that you can still maintain on less than what the site recommends (because everyone is different), but it's good to have an idea of what your new range can be. :D
You might still lose a couple pounds as you adjust, I know I lost another 7 or 8 once I hit goal (was 155), and I have stayed around there for the last 8 months. I've basically kept up the same exercise routine, because it fits in with my schedule, though I sometimes slack on the Sundays. However, my husband, who is also Sparking, kind of coasted the last year, and maintained... now he's getting back on track, so that's helping me slack less on the Sundays. LOL!
